Hello people, can anyone answer me if the CP can solve matrix equations?

I don?t know how to write the symbols, so i will try to explain.

if i define a matrix (Matrix1 : 2x2 ) with any values , and another (Matrix 2 : 2x2) with x,y,z,w and a 3rd matrix (Matrix 3 : 2x2) with the results. can i do this:

(Matrix 1) x (Matrix 2) = Matrix 3

if it is possible, please explain to me how.

Thanks

Hi there

As far as I know CP doesn't have a function to solve matrix equations, but I have written one myself.

mSolve(A,=A^(-1)*B

where A and B are matrices. If you put your Martix 1 instead of A and Matrix 3 instead of B you'll get the solution martix 2 It works great when you want to solve a system of linear equations given in a matrix form Ax=B, where A is the matrix of coeficients, x is a column vector of the unknowns and B is a column vector of the right sides of the equations. Hope this solves your problem

It's:

mSolve(A,B)=A^(-1) * B

mSolve(A,B)=A^(-1) * B

Thanks a lot m4x, i didn't try yey, but i'm shure that it works fine.

Thanks a lot

Actually you can do the AxB = C..

- Go to Main Mode,

- Turn on the Soft keyboard,

- Tap on 2D,

- You see a down arrow at the bottom-middle of the soft keyboard, tap on it,

- You will see the matrix icon.

the top left icon is to add column, the top middle for adding row and the top right is for defining a 2x2 matrix.

cheers,

mc
